the first step after removing the axle, is to remove the hub.
use the SIR tool as described in page #1 in the manual.
i know that some succeeded in installing the "horseshoe" part without removing the e-brake pads. didn't work for me.
this is the setup from the front.
and from the back
when the hub comes out, the bearing will brake apart and the inner race will stay on the bearing.
the hub has to grooves in it, that will allow you to insert the hands of the bearing puller, as described in earlier posts in this thread.
once removing the inner race of the bearing from the hubs, i placed the hubs in the freezer.
